Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 to FIG. 5.

FIG. 1 is a coupling configuration diagram of the backpack frame according to an embodiment of the present invention.

First, with reference to FIG. 1, a backpack frame 100 according to an embodiment of the present invention may be formed to maintain a shape of the backpack 10 by being mounted on a backpack 10 including a frame bag coupling device 50.

Specifically, since the frame bag coupling device 50 is a device that is coupled with the back of the backpack 10 in contact with the back of a person, the frame bag coupling device 50 may be formed as a shape corresponding to the rear surface of the backpack 10. For example, as illustrated in FIG. 1, when the rear surface of the backpack 10 is tapered inwardly from the top to the bottom, the frame bag coupling device 50 may also be inwardly tapered from the top to the bottom so as to correspond thereto. At this time, coupling between the frame bag coupling device 50 and the backpack 10 is not limited, but it is preferable that it is coupled and fixed as a bar.

Meanwhile, a frame upper coupling portion 60 may be formed at the top of the frame bag coupling device 50 and a frame lower coupling portion 70 may be formed at the bottom.

Specifically, the frame upper coupling portion 60 may be formed in a form that the diameter narrows toward one side in order to be coupled with an upper frame 120 of the backpack frame 100. This is a shape for fixing the upper frame 120 of the backpack frame 100, and when the backpack frame 100 is inserted into the frame upper coupling portion 60 through a lower portion, and the frame upper coupling portion 60 is turned over. Preferably, before turning it over, the diameter is narrowed toward the upper side so that it is easy to insert, and after turning it over and the diameter is narrowed toward the lower side, thereby preventing the backpack frame 100 from being separated from the lower side of the backpack by gravity.

At this time, it is preferable that the frame upper coupling portion 60 has a diameter smaller than the length of the upper frame 120 of the backpack frame 100 in order to support the upper portion of the backpack frame 100 and a diameter corresponding to a width of the upper portion of the coupling frame 140 in the backpack frame 100 is formed in order to fix well onto the backpack frame 100. In addition, it is preferable that a part of the upper portion of the frame bag coupling device 50 including the frame upper coupling portion 60 is not fixed to the backpack so that it can be turned over.

The backpack frame 100 will be described in detail below with reference to FIG. 2.

The frame lower coupling portion 70 may include a strap adjuster 72 in order to be coupled with a lower frame 160 of the backpack frame 100. Here, the strap adjuster 72 is connected with the strap, and passes through a binding hole 162 of the backpack frame 100 (which will be described below), and then tightly couples a lower portion of the backpack frame 100 with a lower portion of the frame bag coupling device 50 by a strap.

By doing so, a shape may be maintained so that the backpack 10 does not sag, by tightly coupling the upper and lower coupling portions 60 and 70 of the backpack frame 100 with the frame bag coupling device 50 by upper and lower coupling portions 60 and 70 of the backpack frame.

Hereinafter, the backpack frame 100 will be described in detail with reference to FIG. 2 to FIG. 4.

FIG. 2 is a perspective view of the backpack frame according to an embodiment of the present invention, FIG. 3 is a diagram illustrating a configuration example in which the backpack frame according to an embodiment of the present invention is formed to adjust upper and lower positions of a shoulder belt in order to improve an user's convenience, and FIG. 4 is a diagram illustrating a configuration example in which the backpack frame according to an embodiment of the present invention is formed to mount a waist support member in order to improve the user's convenience.

First, with reference to FIG. 2, the backpack frame 100 may include the upper frame 120, the coupling frame 140, and the lower frame 160.

Specifically, as described above, the upper frame 120 may be fixed by being coupled with the frame upper coupling portion 60 formed at the top of the frame bag coupling device 50. At this time, the upper frame 120 may be formed in the form of a horizontal bar having a length larger than the diameter of the upper frame coupling portion 60 to prevent departure to the lower side. That is, it is implemented as a structure in which the bottom of the upper frame 120 is mounted on the top of the frame upper coupling portion 60.

The coupling frame 140 may be coupled with the upper frame 120 in a longitudinal direction. In addition, the coupling frame 140 is formed to taper toward the center of the backpack frame 100. At this time, although the coupling frame 140 may be coupled with the upper frame 120 in a tapered flat form, but as illustrated in FIG. 2, a center hole may be formed so that two tapered bars are coupled with the upper frame 120. That is, a shape of the coupling frame 140 is not limited thereto, and it is sufficient that both sides are tapered so as to facilitate insertion into the frame upper coupling portion 60.

The lower frame 160 may be coupled with the coupling frame 140. In addition, the lower frame 160 of a flat plate shape is formed. In addition, the binding hole 162 capable of binding the strap adjuster 72 equipped together with a strap of the frame lower coupling portion 70 may be formed at the lower portion of the lower frame 160.

Here, as illustrated in FIG. 2, the binding hole 162 may be formed as a straight long hole in a horizontal shape. This is for allowing the strap adjuster 72 to pass through, but the shape is not limited thereto, and a shape in which the strap adjuster 72 can pass through, is sufficient. By doing so, the lower frame 160 may be fixed by being tightly coupled with the lower portion of the frame bag coupling device 50.

Meanwhile, the backpack frame 100 according to an embodiment of the present invention may be formed to be able to adjust a position of the shoulder belt of the backpack 10 in order to improve the user's convenience and to mount the waist support member 180. This will be described in detail with reference to FIG. 3 and FIG. 4.

In this regard, with reference to FIG. 3, the backpack frame 100 according to an embodiment of the present invention may be formed to be able to adjust the upper and lower positions of the shoulder belt of the backpack 10 in order to improve the user's convenience.

For this, a long hole 142 a or a gear rail 142 b may be formed at both sides of the coupling frame 140. In addition, a fixing member may be coupled with the shoulder belt 15 of the backpack 10. At this time, the long hole 142 a or the gear rail 142 b may be formed vertically along a length direction of the coupling frame 140. In addition, the fixing member may include a T shape fixing member 144 a when the long hole 142 a is formed, and a gear fixing member 144 b may be provided when the gear rail 142 b is formed.

That is, the T shape member 144 a and the gear fixing member 144 b coupled with the shoulder belt 15 of the backpack 10 are guided up and down by the long hole 142 a and the gear rail 142 b of which each form a length vertically, so that upper and lower positions of the shoulder belt 15 of the backpack 10 may be adjusted.

Meanwhile, when the T shape fixing member 144 a is provided by forming the long hole 142 a, it is preferable that the T shape fixing member 144 a is formed rotatably to be prevented from being separated after inserting into the long hole 142 a. That is, since the T shape fixing member 144 a is rotatably formed, it may be inserted vertically when being inserted into the long hole 142 a, and it is possible to prevent separation from the long hole 142 a by being rotated horizontally after the insertion.

In addition, when the T shape fixing member 144 a is provided by forming the long hole 142 a, a Velcro (not illustrated) may be provided in each of the shoulder belt 15 of the backpack 10 and the coupling frame 140. This is for fixing the belt and the frame by using the Velcro (not illustrated) after the adjustment of the upper and lower positions of the T shape fixing member 144 a.

In addition, with reference to FIG. 4, the backpack frame 100 according to an embodiment of the present invention may be formed to mount the waist support member 180 in order to improve the user's convenience.

For this, a bearing coupler 164 corresponding to a spherical bearing 170 may be formed at the lower frame 160. Here, the spherical bearing 170 may be coupled with the waist support member 180. That is, it is possible to improve the user's convenience by mounting the waist support member 180 on the bearing coupler 164 through the spherical bearing 170.

Specifically, the spherical bearing 170 may be formed of two bushing couplers. One of these is a first bearing bushing 172 coupled with the waist support member 180 and the other is a second bearing bushing 174 coupled with the bearing coupler 164. At this time, an outer surface of the first bearing bushing 172 may be formed in a spherical shape and an inner surface of the second bearing bushing 174 may also be formed and coupled in the spherical shape corresponding to that of the first bearing bushing 172. That is, the first bearing bushing 172 may be rotated along the spherical surface inside the second bearing bushing 174 by being coupled on the inner surface of the second bearing bushing 174.

By doing so, the waist support member 180 may be rotated according to the first bearing bushing 172. Accordingly, since the waist support member 180 is rotated together according to the waist movement of the user, there is an effect where it is possible to increase convenience.

Here, in a case of the second bearing bushing 174, it is preferable that the bushing is fixed so as not to move because it is mounted on the bearing coupler 164. For this, the bushing may be mounted on the bearing coupler 164 with a fixing device or the like according to a shape of the second bearing bushing 174. However, the shape is not limited thereto, the fixing device or the like may be formed with the second bearing bushing 174.

Meanwhile, the first and second bearing bushings 172 and 174 are may be formed integrally or prefabricated, and when one is formed integrally, the other may be prefabricated.

That is, as illustrated in FIG. 4, when the first bearing bushing 172 is formed integrally, the second bearing bushing 174 may be formed prefabricated. On the contrary, when the first bearing bushing 172 is formed prefabricated, the second bearing bushing 174 may be formed integrally. This is to facilitate the coupling between two bushings 172 and 174.

In addition, when the first and second bearing bushings 172 and 174 are coupled with each other, a bolt or the like may be used for coupling, and when the first bearing bushing 172 and the waist support member 180 are coupled with each other, it is possible to couple them to prevent separation by coupling with an auxiliary coupler or the like together.

Meanwhile, in a case where the first bearing bushing 172 is coupled with the waist support member 180, the member may be protruded to bend over the user's waist for buffering the user's waist. In addition, the waist support member 180 may be formed of a plastic material or carbon fiber material to have elasticity.

In addition, the backpack frame according to an embodiment of the present invention may be processed as a carbon fiber material. At this time, the carbon fiber material may be formed of a mixture of a tow cut into carbon fibers 25 mm to 30 mm in length and vinyl ester resins, wherein the mixture may be 50% to 55% by weight relative to the total weight of the backpack frame.

In addition, the processing of the carbon fiber material may use a forging press of a warm forging method, a processing heat temperature in a mold may be 130° C. to 160° C., working pressure is 70 bar to 105 bar, and a curing time may be 1 minute to 5 minutes.

However, the carbon fiber length, the mixture weight percent, the processing heat temperature, the working pressure, and the curing time are not limited to the examples.

Hereinafter, with reference to FIG. 5, a coupling method between the backpack frame 100 and the frame bag coupling device 50 coupled with the backpack 10 according to an embodiment of the present invention will be described.

FIG. 5 is a diagram illustrating the coupling of the backpack frame according to an embodiment of the present invention.

With reference to FIG. 5, in a coupling method of the backpack frame according to an embodiment of the present invention, the backpack frame 100 may be inserted into the frame upper coupling portion 60 formed at the top of the frame bag coupling device 50 in a direction of the lower frame 160 to view the rear surface of the backpack frame 100. At this time, the backpack frame is inserted until it is in contact with the upper frame 120 of the backpack frame 100.

If the backpack frame is inserted until it is in contact with the upper frame 120, the upper portion of the backpack frame 100 is fixed by inverting the backpack frame 100 and the frame upper coupling portion 60 to view the front of the backpack frame 100.

Then, when the strap adjuster 72 coupled by the strap of the frame lower coupling portion 70 passes through the binding hole 162 formed at the lower portion of the backpack frame 100 and the strap is pulled by passing the strap through the strap adjuster 72 in a zigzag manner, the lower portion of the backpack frame 100 may be fixed. By doing so, the backpack 10 and the backpack frame 100 may be tightly coupled with each other.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will appreciate that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Accordingly, the embodiments described above are exemplary in all respects and not restrictive.
